The nature of my invention relates to mechanism for guiding, supporting, and operating a turning-tool within a hell, or other hollow casting, and alsoforcentering the bell and sustaining it'in position. i The following is a description of one practical-mode of carrying my invention into efi'ect:

V In the accompanying drawing; v

A represents a solid foundation, on which the hell Rand its turning devicesaresustained.

l B are posts, which rise perpendicularly from the foundation 5- a suitable height, and have bolted to their upper ends a horizontalpiece, B, which, with the posts, constitute aframe for supporting several of the workingparts of the machine.

Two short posts, cc, rise from head-piece B, and

afford bearings for a horizontaldriving-shaft,0, carv rying a beltspnllcy, G, on one end.

On' this shaft 0 a pinion bevel-wheel, l), is keyed,

which engages with a wheel,fb, on a vertical shaft,D, and gives rotary inotion'thereto.

The shaft D liasitsupper bearing in the head-piece B, and at its lower end it is-supported by a step upon the inner side and in .thecen ter of the bell R.

g This shaftD carries the cutting or turning-tool m, and the devices which keep to its work of turning out the interior, surface of a bell. The turning-tool m is adjustableendwise, and is thus adjusted bymeans of a screw, P, which has a collar, '0, on it, that entersa notch formed in the shank of thetool m, asshown in fig. 4. r

- The adjusting-screw P and also the tool Lon are applied to a vertically-adjustable block,jP, which latter is applied to'a 'ho'rizontally-adhistable block, G, which i is applied to a .ertically adj' stable horizontal rest, E,

The block P is connected tobloc-k Q by dovetailguides h h, and adjustedby means of :usogcw, J, carrying on its upper end a tappet-wheeL J',which-is acted upon, at every revolution of shaft 1), by an .adjustable striker, j, attached to the head-piece B.

To the vertically-adjustable block P a feed-wheel,

w, is applied, which rolls against the inside of thebell' If. during the operation of the machine, and follows the turning-tool, so as to prevent vibration thereof. rawing making part the rest E by means of adovetailed tenon and groove,

- The horizontally-adjustable block G is applied to so as-to slide on said rest in the direction of its length. Thisblock G is forced outwardly, and the wheel w held against the hell, by meansof a spring, S.

. This spring is coiled around an adj usting-sc1'e w,' 'n,

and confined between a movable nut, (l, and the block a gib. By loosening the screw 1 the rest 13), and all the parts connected to it, can be raised or depressed on the shaft D.

The bell R is centered. and held by means of three side chucks and a collar, a. f

The chucks g g g are adjusted by means of nuts which, with the chucks, are applied tovertically-adj ustable blocks f.

These "blocks f are connected'to radially-adjustable standards k, which are supported by and made adjust able on the foundation A.

Beneath the bellR a collar or step, a is secured to the foundation A, directly in linewith the center of the shaft D, which collar is adapted to'receive into it y the bell-shank 0r hub, and it is provided with setscrewsfor centering and securing the bell down in place.

It will be seen, from the above description, that the centering and chucking devices are adjustable, in or-,

der to adapt them to bells of various sizes.

Operation A bell which is to be toned is inverted, and its shank adjusted into the collar or step a, and confined therein by means of the set-screws, which are applied radially to this collar.

The chuck-blocks and their standards are then adjusted up tothe upper margin of the bell, and the chucks g firmly forced against this margin, care being observed that the bell is centered with respect to the axis of the. shaft D. r r 1 The shaft D is then adjusted into place, and. the

ters Patent, is-

rest E loosened on its shaft, and depressed so as to bring the cutting-tool m at the proper point to commencc work on the bell.

The rest E is then secured fast toth'e shaft D, the tool m is adjusted up to the bell, and the spring S is adjusted so as to keep the tool to its work under the required degree of pressure. Motion is now imparted to the-shaft D, and the tool caused to revolve within the boll.

- Previous to starting the machine the striker j is adjusted so as to give part of a turn to the screw J, atevery revolution of the tool, which will feed the tool down to its work.

Having described one practical mode of toning bells by machinery,

What I claim as new, and desire to secureby Let 1. The combination of l the rotating cutter-carrying shaft and the fixed journal-bearing, to hold the same in position, and to prevent any lateral or endwise play thereof, the cutting or planing tool m, mechanism to impart feed-motion to said tool, to a just it to describe circles of greater or lesser diameter, and to graduate the depth of thecut, and the spring 5, or equivalent device, connected to the tool-holder, or some part connected directly thereto, to force thetool up to its work, and at the same time leave it free to adjust itself, as it traverses the surface of the hell or other article, to the gradually-increasing or diminishing diameter of the hell or other article. i 2; In combination with the cutter 1n,'b1ock G, rest E, and shaft D, arranged as described, the vertical screw J, sliding block P, horizontal tappet-head J, striker j, substantially in the manner and'for the purpose described.

3. In combination with the tool m, block P, block G, rest E, and shaft D, the adjusting-screw P 0, substantiall y iu'the manner and for the purpose described.

4. In combination with the tool m, block P, block G, rest E, and shaft D, the wheel w, (following the cutter,) screw n, and spring 8, substantially in the manner and for the purpose described.

5. The arrangement of the bell-centering and confining chucks g, step a, central cutter-carrying shaft 10, s'ubstant-ially in'the manner and for the purpose described.

. 6. The combination of the base A, adjustable standards K, adjustable holding devices f g g, and stepa, substantially as described.

7.v The improved machine hereinbefore described.
